Change History

I'm not sure this is easily possible - South is entirely written on a per-app basis, and it assumes that each app has all of its model data present in each migration. To change that would be a massive effort, all for saving a little bit of developer coordination - something you'd still need if these "groups" had things like ForeignKeys? which spanned multiple groups.

I'm afraid I'm going to WONTFIX this, on the basis that it's changing what South _is_ fundamentally - if you want separate migration series for different models, they should probably be different apps.
